Abstract

SOPORTE DE TEST PARA EL EXAMEN ANALITICO DE UN LIQUIDO DE PRUEBA CON AYUDA DE UNA REACCION DE ENLACE ESPECIFICA CON DOS ELEMENTOS DE ENLACE BIOAFINES, PREFERENTEMENTE UNA REACCION ANTICUERPO-ANTIGENO. SOBRE UNA CAPA DE BASE (2) ESTAN DISPUESTAS UNA JUNTO A OTRA ZONAS DE TEST (21 HASTA 25) ACTIVO-CAPILARES, QUE FORMAN UN TRAMO TRANSPORTADOR DE LIQUIDO (20), A LO LARGO DE LAS CUALES FLUYE UN LIQUIDO PROPULSADO POR FUERZAS CAPILARES. AL HACERLO, SE PRODUCE UNA REACCION DE VERIFICACION QUE CONDUCE A UNA ESPECIE CARACTERISTICA DEL ANALISIS DESEADO, MOSTRANDO ESTA ESPECIE EN UNA ZONA DE VERIFICACION (26). CON EL FIN DE PONER A DISPOSICION UN SOPORTE DE TEST FACILMENTE MANEJABLE Y PRODUCIBLE A COSTE FAVORABLE, CON UNA ZONA INICIAL QUE SOLO DEBA INTRODUCIRSE BREVEMENTE EN LA PRUEBA Y ENTREGUE DESPUES POCO A POCO EL LIQUIDO DE PRUEBA ABSORBIDO DE FORMA TAL QUE RECIBAN LIQUIDOS LAS ZONAS SECUNDARIAS AL SECTOR FUNCIONAL PROPIO DEL SOPORTE DE TEST, DE FORMA SUFICIENTE Y REPRODUCIBLE, SE PROPONE QUE LAZONA INICIAL (21) SE COMPONGA DE UN FIELTRO FIBROSO QUE NO HINCHE CON UN AGLUTINANTE INSOLUBLE EN AGUA.
